“This legislation would ensure that Arizonans are not forced to pay a penalty due to the failure of a healthcare system that was fatally flawed from conception,” McCain said in a statement.

Arizona is at the forefront of the issue because Pinal County in the state is currently slated to have no insurers offering ObamaCare coverage at all next year, which would be the first time that situation has happened.

The shrinking number of options on the ObamaCare marketplaces has been an area of rising prominence given the high-profile exits by some major insurers for 2017.

The Kaiser Family Foundation estimates that 31 percent of counties will have just one ObamaCare insurer in 2017, up from 7 percent this year.

These counties are concentrated in rural areas, and the analysis estimates that 62 percent of enrollees will still have the choice of three or more insurers, though that is down from 85 percent this year.

“Under Obamacare, Wisconsinites can be penalized for not buying a company’s product, even when there is only one company selling it,” Johnson said in a statement. “This legislation would help ensure that Wisconsin families won't have to pay a penalty to help cover the cost of Obamacare’s failed promise of consumer choice.”
